利用资源三号测绘卫星影像实现多尺度4D产品更新

Achieve Multi-Scale 4D Product Updates by Using the Imageries of the 3rd Resources Mapping Satellite

4D产品的快速生产与更新一直以来是测绘地理信息部门研究的重点,采用传统航摄技术生产和更新无图区或陈旧的地理信息资料时,生产困难,成本高,周期长,且消耗大量的人力和物力。针对这些问题,本文采用资源三号测绘卫星影像实现4D产品更新,使得更新速度加快,为多尺度4D产品的生产与更新提供了高效可靠的技术手段。

The rapid production and updating of 4D products has always been the focus of the research and mapping of geographic information department.When using traditional aerial photography technology to produce and update no map area or old geographic information materials, the production operation is difficult, the cost is high, the period is long, and consume a lot of manpower and material resources.In view of these problems, this paper uses the imageries of the 3rd Resources Mapping Satellite to achieve 4D product updates, making the update faster, multi-scale 4D products for the production and update to provide a highly efficient and reliable technical means.
